Denitrative Formal [5+1] Cycloaddition of 1‐(2‐Nitrophenyl)‐2‐Yn‐1‐Ones with Thioacetamide under Transition‐Metal‐Free Conditions: Synthesis of Thiochromen‐4‐Ones

A new strategy for thiochromen‐4‐one synthesis that relies on the denitrative formal [5+1] cycloaddition of 1‐(2‐nitrophenyl)‐2‐yn‐1‐ones with thioacetamide is described. Achieved under reaction conditions that did not require transition metal catalysis, nor the exclusion of air or moisture, the rea...
